BRAIDING MACHINE.

Application filed october 27, 1925. Serial No. 65,197.

This invention relates to an improved construction of braiding machines of the class provided with oscillating carriers; and has for its object to provide in such a machine two cooperating spaced raceway plates having raceways of different contours, the carriers being mounted in the raceways of both plates and driven by gears mounted below both of saidraceway plates.

A further object of this invention is to provide carriers of the oscillating type having portions guided in both of the raceways and also having an extended portion guided between these raceway plates so as to support that portion of the carrier abovethe plates in an upright position.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims. y

In the accompanying drawings: Figure 1 is a top view of this improved braiding machine, showing portions of the two upper raceway plates as broken away to expose the driving gear and also the sup porting plate below.

It is found in practice in the operation of braiding machines in order to obtain a high degree of speed, of advantage to reduce the extent of oscillation or in and out motions of the carriers relative to the braiding center, which style of machine the advan tage of reducing the travel of the yarn ten sion weight and thereby reduce the friction on the yarn, which weight travel tends to remove the lustre. particularly on yarns having glossy or finished surfaces such as artificial silks and the like commonly known as Rayon; and to obviate this detrimental effect, I have provided a machine of simple and practical construction that has two cooperating narrowly-spaced plates having raceways of different contours, in both of which raceways parts of the carrierl are caused to run, the neck portion of the carrier engaging the upper raceway while the shoe portion thereot is arrangedto ea:-

tend down throughthe lower raceway plate to be engaged and operated by the usual train of carrier driving gears which, in this case, are located below both of the raceway plates. By this construction, I am enabled to readily convert the ordinary braiding machine having a single racewayplate with the old type of carrier, into a braidingmachine of the oscillating carrier type, by simply mounting an upper raceway plate having raceways of less in and out contours, whereby the oscillating carrier maybe readily mounted to operate between these two raceway plates to produce the desired oscillating effect; and the following is a detailed description of the present embodiment of my invention and showing one means by which these advantageous results may be With reference to the drawings, 10designates the upper raceway plate in which is formed the raceways 11 being relatively slightly oii'set from either side of a. central line through them to reduce the oscillating action of the upper portion of the carrier. Spaced from this upper plate is the lower raceway plate 12 which is held in set spaced relation by the spacer washers 13 through which the bolts 14 pass. This plate is provided with raceways 15 which have a more pronounced contour than those of the upper raceway plate. i

Spaced from this lower raceway plate'is the base plate 16 which is held in spaced relation by the spacers 17 and secured by the bolts 14. Supported on thislower plate 16 on the central studs 18 is a train of carrier driving horn gears 19 each of which is pro vided with arms or horns 20 to engage and drive the carriers 21.

These carriers are provided with the usual package carrying spindle 22 and weight guide 23 also with a guide neck portion .2

having a guide member 25 loosely mounted thereon, which guide member is preferably formed of steel and is split as at 26 whereby it is adapted to be opened or sprung apart suiiiciently to receive the neck portion 24: in its bore 26 and then closed together to be loosely mounted on the neck and so provide a suitable guide for this portion of the carrier in the upper raceway.

In order to support this carrier against a lateral tipping motion,"I have formed a broad or extended foot member 27 which extends along in the space between the upper and lower raceway plate. This circular flange is also adapted to extend into an opening 32 in the guide foot 27 of the car rier to loosely engage the same, whereby the foot is pivotally connected to the shoe member to be operated thereby without cramping.

By my improved construction of braiding machines, when it is desired, the usual or old style machine which comprises the lower or base plate 16 on which the horn gears are mounted and the lower raceway plate 12, may be readily converted into a braiding machine of the oscillating carrier type, by mounting the upper raceway plate 10 thereon having raceways of the desired contours and mounting the same in narrow-spaced relation above the raceway plate 12 and then by providing a set of carriers of the type above described this machine may be operated as a braiding machine of the oscillating type.

In some instances, instead of providing a broad flat guide foot 77 which is guided between 'the plates 10 and 12, I may space the plates wider apart and guide the foot 39 on the pin 40 of the shoe 41, as illustrated in Figure 8.

I do not wish to be limited to the use of two separate raceway plates, as a single raceway plate 33 having two raceways including the inner groove 34 and the slot 35 both formed therein. as illustrated in Figures 9 and 10, may be employed, if desired, which arrangement of parts will produce the desired oscillating eiiect in the carrier 36 which has a guide finger 37 running 'in the inner groove 34: and a guide shank 38 extending through the slot 35, the latter to be engaged and operated by a horn gear or other driving mechanism, not shown.

My improved braiding machine is very simple and practical in construction and is effective in its operation.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
